Problems solved by technology

[0002] In recent years, the price of grass carp has continued to slump, the cost of feed is high, the efficiency of farming is low, and even losses have caused loss of confidence in grass carp farming, while the price of bighead carp has risen steadily in recent years. Secondly, in recent years, lakes, reservoirs, rivers, etc. Fish farming has been banned in the local area, and the output of bighead carp has dropped significantly, resulting in a shortage of bighead carp in the market and high prices. However, there are some shortcomings in the existing bighead carp breeding process that need to be innovated. The first is the growth rate of bighead carp. Fast, with natural plankton as food, but in the process of the existing bighead carp pond culture method, the plankton is quickly preyed on by the bighead carp in the pond, which leads to the inability of the plankton to reproduce sustainably and quickly , resulting in the lack of food and slow growth of bighead carp in aquaculture. Therefore, we have made innovations and proposed a low-cost and high-efficiency method of feeding bighead carp with plankton in ponds

specific Embodiment approach

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiment is a specific implementation of the present invention, and is not limited to all the embodiments.

[0019] Therefore, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely represents some embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0020] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features and technical solu...

specific Embodiment 1

[0021] Specific embodiment 1, such as figure 1 , a low-cost and high-efficiency method for cultivating bighead carp ponds fed on plankton, including S1, setting up a culture pond and setting an inlet and drainage system; S2 setting a bighead carp breeding area and a plankton breeding area, the bighead carp breeding area Polyethylene net sheet is set between described plankton breeding area, in described S2, intercept 30% waters of pond total area with the polyethylene net sheet of 1-1.5 centimeter mesh in the northern part of pond as zooplankton culture area, remaining 70% of the water area belongs to the bighead carp breeding area, and the bottom of the net is 15 cm into the mud to ensure tightness. The net is 1 meter above the highest water surface, and a waterwheel type aerator is installed in the bighead carp breeding area 8-10 meters away from the isolation net, and every 10 mu of pond is equipped with an impeller type aerator with a power of 3 kilowatts; After the S3 cl...

specific Embodiment 2,1

[0026] Specific embodiment 2,1. Pond condition, culture pond, area all can be with 10~50 mus, and average depth of water is advisable with 2 meters. The water inlet and drainage system is complete; the water source is fresh and pollution-free, in line with the national fishery water quality standard. 2. The clear pond is disinfected, and the pond water is drained at the beginning of the year to remove excess silt. Leave 15 cm thick silt at the bottom of the pond and dry the pond for 8 to 10 days. day, and then disinfect with quicklime at a dosage of 100 kg / acre. In places where there is a lot of bottom mud, it should be turned properly to ensure thorough disinfection. 30% of the total area of ​​the pond is used as a zooplankton culture area, and the remaining 70% of the water area belongs to the bighead carp culture area. The bottom of the net is inserted into the mud by 15 cm to ensure tightness. The net is 1 meter above the highest water surface, and a waterwheel type aerat...

Abstract

The invention provides a low-cost and high-efficiency aristichthys nobilis pond culture method with plankton for feeding, which comprises the following steps: by adopting a pond main culture mode of aristichthys nobilis, intercepting a 1 / 3 water surface in the pond by using a net to specially serve as a breeding and culturing area of plankton, separating an aristichthys nobilis culture area from a plankton breeding area, and separating the aristichthys nobilis culture area from the plankton breeding area; the breeding capacity of the zooplanktons is greatly improved, the zooplanktons can continuously flow to the bighead carp breeding area through the meshes to be ingested by the bighead carps when reaching a certain density, organic fertilizer is frequently applied to the plankton breeding and culturing area, the quantity of the planktons is continuously bred to the maximum extent, and therefore the yield of the bighead carps is increased; the water quality is regulated and controlled through methods such as a microbial preparation and the like, so that space bacterial phase balance and excellent water quality for fish survival are ensured, fish diseases are reduced, meanwhile, water body exchange is reduced, water sources are saved, pollution emission and energy consumption are reduced, and the quality of commercial fish is improved.
